Answer:
C. Disruptive Selection
Explanation:
Disruptive selection occurs when two extremes of continuous variation are favored more than intermediate traits.  
The extremes of continuous variation exhibited in this species of snail is the color of their shell which allows them to blend with the background of their habitat.  
The shady forest of the habitat makes the dark-shelled individuals to be better hidden from bird predators, while the light-shelled individuals are better hidden in well-lit brushy edge areas. This disruptive coloration exhibited by both individuals makes both individuals of this species of snail less vulnerable to predation.  
Both individuals of this species both extremities would naturally survive in this habitat as snails with intermediate extremities would be highly preyed on since there is no area of intermediate brightness in the habitat to make them invisible to predators
 
        
             
        
        
        
Nonselective catheter placement
 This can also be placed only into the aorta from any approach. Catheter placed into the arterial vessel and not manipulated to another arterial site. This also refers to the catheter that remains in the accessed vessel or that has made it into the aorta. In contrast to the selective catheter placement which is placed into a branch off the aorta or access the vessel. Each vessel arise from the aorta represents different vascularities.
        
             
        
        
        
Answer:
Professional gardeners often soak seeds in hydrogen peroxide before planting them in order to increase the germination percentage or to reduce germination failure. When the seeds are soaked in hydrogen peroxide, the seed coat becomes soft and enzymes present in the seed becomes active. Due to soaking of seeds, the seed takes less time to germinate. So that's why gardeners uses this method. 
 
        
             
        
        
        
Answer:
As the generations are increasing or gets much over time, we have a more likelihood of seeing a response to natural selections as the favourable alleles are going to be moved from one generation to the next while those that are not favourable would be eliminated over generations.
If the new host gives allowance for early reproduction and ease of access then the generations each year would rise.
 
        
             
        
        
        
When a substance abuse treatment program is acquired by another program, the next course of action is that <u>if any patients refuse consent to transfer, those records maybe destroyed or retained in compliance with the statue of limitations</u>
Explanation:
The Substance Abuse Confidentiality Regulations devised by the Substance Abuse and Mental Health Services Administration provides confidentiality to the patients undergoing a treatment program for substance abuse.  
Under this regulation, section 2.19 details and sets forth rules to follow when a program is acquired by another program. 
This states that the program must either purge the identifying details of the patient from its records or destroy it until or unless the patient consents for the transfer of details or information in the records.
This condition can be exceptional in compliance with the statute of limitations and the records can be retained, like in case of any legal requirements
